I'd love to see a TV Space Opera based on Martin's Haviland Tuf series or McDevitt's Priscilla Hutchins series, but neither one is violent enough (and the last Tuf story was actually a parody of that when he returned to a planet to find that his prior adventure there had been twisted into an Abrams-style movie). The best bets for turning a classic Space Opera into a TV series are probably Niven's Known Space, Smith's Lensman series or de Camp's Planet Krishna. Australis would no doubt add Banks' Culture Series, and I wouldn't disagree with that.
